Oracle WebLogic Server 12c has an exiting new feature called Dynamic Clusters. WebLogic Server dynamic cluster contains multiple dynamic servers that is based on a single server template. This template contains the base configuration of the servers in a dynamic cluster and will be the basis for all the servers in the cluster so that each server does not need to be manually configured when expanding the cluster. You just specify the number of server instances on a peak load and let the Oracle Weblogic Server takes care of the rest.
